Independent presidential candidate Robert F. Kennedy Jr. sought a meeting last week with Democratic nominee Kamala Harris to discuss the possibility of serving in her administration, perhaps as a Cabinet secretary, if he throws his support behind her campaign and she wins, according to Kennedy campaign officials.

Harris and her advisers have not responded with an offer to meet or shown interest in the proposal, say people familiar with the conversations.

The Kennedy outreach, made through intermediaries, follows a meeting in Milwaukee last month between Kennedy and Republican nominee Donald Trump to discuss a similar policy role and endorsement that resulted in no agreement. In those discussions, Kennedy spoke about advising Trump in a second term on health and medical issues.
